Using the following equation, please find the center and radius of the circle. I would greatly appreciate if you showed your work. Cheers! :) x^2 − 4x + y^2 + 8y = −4

1,8,15,22,29,36,43,50

step-by-step explanation:

correct answer is b. 27/8

step-by-step explanation:

hope this !

let me know

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
